  • Patent number: 4213632
    Abstract: An independently suspended wheel rear axle suspension for motor vehicles of the torsion spring type is improved by the provision of a bolster that is designed for reducing the suspension space requirements, while providing optimal noise damping and stable wheel guidance. The improved bolster includes, according to a preferred embodiment, a thrust bearing, a rigid longitudinal support that is connected to the vehicle body by the thrust bearing for providing only vibration insulation and guiding, a support bearing, and a resilient spring member connected to the vehicle body by the support bearing for receiving the preponderant torque of the torsion spring and the vehicle weight, while providing vibration insulation. The longitudinal support means is mounted so as to be elastically displaceable under the influence of forces in the vehicle longitudinal direction, while being relatively rigid under the influence of forces in the vehicle transverse direction.
